问题描述
我正在尝试从 git 安装一个新的 Django 项目，我使用创建了一个新的虚拟环境 python3（版本：3.8.5）。当我尝试在 requirements.txt 中安装所需的库时，我收到 cffi==1.11.5 包的以下错误。

我已经遵循了有关 stackoverflow 的一些建议，但这似乎不起作用。 我已经尝试过的事情。 Failed to install Python Cryptography package with PIP and setup.py
sudo apt-get install build-essential libssl-dev libffi-dev python3-dev
我正在使用 Ubuntu。请让我知道我做错了什么。
